BOSE-EINSTEIN CORRELATIONS IN THE LUND MODEL
Talk given at the XXV Multiparticle Symposium
I will present a generalisation to identical multi-boson states of an earlier
model~\cite{WernerBo}, for the Bose-Einstein correlations, which are inherent in
a quantum-mechanical interpretation of the Lund Fragmentation Model. The
resulting formulas are for simplicity applied to a toy model, only containing
three (charged) boson species (``the pions'') and one non-bosonic hadron. (There
is now a computer program in C++, available on request from Markus Ringn\'er,
which may be used to obtain the general results from the Lund Model as
implemented by JETSET). The resulting predictions imply a difference for the
$\pi^0$ correlations (two $\pi^0$'s can be produced as neighbours in rank)
compared to the charged $\pi^{\pm}$, which cannot be neighbours in rank. The
model also exhibits irregularities in small rapidity bins,of the kind which
has been termed ``intermittency''.
